Good app but could be better – Pool-Calculator Review

I like the app and use it everyday. It really helps keep track of my chems. The only thing I can think of to make it better would be a box to add notes for the test. E.g. I like to check my total chlorine and my phosphates. There are no fields for those. I'm sure if you put every test possible the app would not be reasonable to use but if there was a field to add a quick note, that would make it easier to keep track of other values. But it's a great app!?
